The muscles in the vagina weaken naturally over time, or after events including childbirth. That can lead to urinary incontinence. That’s why Greves says that pelvic floor-strengthening exercises are so crucial. Besides helping to improve bladder control, Sania JIjaz, MD says that kegels can increase vaginal tightness. Yup, kegels can increase your sexual pleasure by giving you stronger, more intense orgasms.When you’re not turning to kegel balls to treat incontinence or tighten your vagina, you can even use them as sex toys, says Jess O’Reilly, PhD, host of the @SexWithDrJess Podcast. “You might insert the balls and rotate or gently tug on the strings to create a range of sensations,” she explains. “Some people enjoy pulling them out very slowly to heighten awareness and bring attention to the more subtle sensations.” To take these sensations up a notch, try running your balls under cool or warm water before inserting them. “Changes in temperature can heighten arousal and change the way we interpret pleasure by activating the body’s sensitive thermoreceptors,” O’Reilly adds.
